The degradation behaviors of the TiV-based multiphase hy.rogen storage alloy.Ti0.8Zr0.2V3.2Mn0.64 Cr0.96Ni1.2 during electrochemical cy.ling in alkaline electroly.e have been studied by.XRD, SEM, EIS and AES measurements. XRD analy.is indicates that the alloy.consists of a C14-ty.e Laves phase and a V-based solid solution. The lattice parameters of both phases are increased after discharged with cy.ling, which indicates that more irreversible hy.rogen remains not discharged in the alloy. It shold be responsible for the decrease of discharge capacity. SEM micrographs show that after 10 electrochemical cy.les, a large number of cracks can be observed in the alloy. existing mainly.in the V-based solid solution phase. Moreover, after 30 cy.les, the alloy.particles are obviously.pulverized due to the larger expansion and shrinkage of cell volumes during hy.rogen absorption and desorption, which induces the fast degradation of the TiV-based hy.rogen storage alloy.. EIS and AES measurements indicate that some passive oxide film has been formed on the surface of alloy.electrode, which has higher charge-transfer resistance, lower hy.rogen diffusivity. and less electro-cataly.ic activity. Therefore it can be concluded that the pulverization and oxidation of the alloy.are the main factors responsible for the fast degradation of the TiV-hased hy.rogen storage alloy..

The transfer kinetics of phenol between aqueous phase and N,N di(methy. hepty.) acetaminde (N503) in kerosene has been studied using Lewis cell technique. The effects of the factors including the concentrations of phenol in aqueous phase and organic phase, the concentration of N503 in organic phase, the acidity.of aqueous phase, the stirring speed and the temperature on the rates of forward and backward extraction of phenol have been examined. The regularity.of extraction rate has been obtained. According to experimental results, the rates of both forward and backward extraction of phenol might be controlled by.diffusion process. The diffusion step of phenol from aqueous phase to interface for forward extraction and from interface to aqueous phase for backward extraction might be the rate controlling steps.

Carbon nanotubes(CNTs) have garnered great attention in recent y.ars due to their outstanding electrical, thermal, and mechanical properties. The incorporation of small amounts of CNTs in poly.ers can substantially.improve the sensitivity.of the poly.er's electrical conductivity. This paper presents a modified Maxwell model to evaluate the electrical conductivity.of CNTs-filled poly.er composites by.introducing a transition zone to account for the tunneling effect. In this modified Maxwell model, the CNTs-filled poly.er composite is modeled as a three-phase composite, consisting of a matrix(poly.er), inclusions(CNTs), and a transition zone(tunneling zone). The effective electrical conductivity.EEC) of the composite is calculated based on the volume fractions and electrical conductivities of the matrix, inclusions, and transition zone. The model's validity.is confirmed through the use of available test data, which demonstrates its capability.to accurately.capture the nonlinear conductivity.behavior observed in CNTs-poly.er composites. This study.offers valuable insights into the design of high-performance conductive poly.er nanocomposites, and enhances the understanding of electrical conduction mechanisms in CNT-dispersed poly.er composites.
